Abstract

The present invention relates to a process for recovering polyhydroxyalkanoate from a biological source material comprising the polyhydroxyalkanoate, the process comprising: a) comminuting the biological source material; b) air classifying the biological source material such that the polyhydroxyalkanoate particles are separated from other components of the biological source material; and c) recovering the polyhydroxyalkanoate.
